The reel winch, available in carbon and
aluminium, stores the line in a single layer to
prevent a second layer from jamming in the
first layer. The calculation for the drum length
is based on the line diameter and the length
of line to be stored, i.e. the retrieving length.
Next to the drum is a spindle-driven slider
to ensure that the line turns are stored
properly. Spindle is driven by pulleys which
are interchangeable enabling adjustments to
the line diameter if necessary. End switches
safeguard the use of the winch. The winch
will stop as soon as all but the (e.g. 3) safety
windings of line have been paid out and it will
also stop as soon as the drum is full.
Underneath the drum, there are sensors that
detect slack in the line, resulting in the drum
stopping when slack is detected.
To prevent slack in the line, all Rondal
winches are equipped with an optical
sensor. This sensor transmits a light beam
underneath, close to the drum. If the line
slackens, the turns around the drum will
drop and interrupt the beam, generating an
electrical signal that will stop the winch. At
the same time, a signal indicating failure
of the winch operation is dispatched to the
steering position. The reel winch is available
with the spindle on either the left- or righthand
side of the drum. The gearbox and brake
are located inside the drum, and connected to
the motor right next to the drum.
